Description

A crystal coating structure Technical Field

[0001] This utility model relates to the field of crystal coating technology, and in particular to a crystal coating structure. Background Technology

[0002] Crystal, as an important decorative material, is widely used in jewelry, footwear, handicrafts, clothing, and leather goods. Through meticulous grinding, polishing, and cutting processes, crystal achieves a dazzling, iridescent appearance similar to natural diamonds. As an embellishing material, crystal, with its unique optical properties and aesthetic appeal, occupies a significant position in the modern decoration industry, and market demand continues to grow. Especially in high-end products, the brightness and luster of crystal have become important indicators of product quality.

[0003] To enhance the optical properties of crystal, surface treatments are typically applied. One approach is to deposit a silver or aluminum layer directly on the base or surface to improve reflectivity, mimicking the refraction and reflection effects of diamonds. Another approach is to apply a lacquer coating to achieve the natural appearance of crystal. However, due to insufficient bonding strength between these coatings and the crystal substrate, they are prone to peeling off with prolonged use or under external force, affecting product quality and lifespan. Summary of the Invention

[0004] In order to optimize the coating structure design of crystal, improve the bonding strength between the coating and the crystal substrate, and enhance optical performance, thereby significantly improving the durability and aesthetics of the coating, this application provides a crystal coating structure.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A crystal coating structure includes a crystal substrate, the upper surface of which has a multifaceted structure and the lower surface of which has a planar structure. An adhesive layer, a reflective layer, and a dielectric layer are disposed on the lower surface of the crystal substrate. The adhesive layer is located between the crystal substrate and the reflective layer. Multiple reflective and dielectric layers are provided and are alternately stacked.

[0007] By employing the aforementioned device, the adhesion layer significantly enhances the bonding strength between the coating and the crystal substrate, effectively solving the problem of easy coating peeling in existing technologies, thereby improving product lifespan and reliability. The reflective layer enhances light reflection, allowing light to be reflected back to the observer's eye more efficiently after refraction within the crystal substrate, thus enhancing the overall brightness and brilliance of the crystal. The dielectric layer has excellent anti-reflective properties, effectively reducing light loss during interlayer propagation and increasing light transmittance, resulting in a purer and more transparent visual effect for the crystal. The alternating stacking of the reflective and dielectric layers forms a multi-layered optical interference structure, which not only improves reflection efficiency but also enhances color saturation and layering, thus allowing the crystal to exhibit a more dazzling and colorful optical effect.

[0008] Preferably, the reflective layer includes a first reflective layer, a second reflective layer, and a third reflective layer, and the dielectric layer includes a first dielectric layer and a second dielectric layer, wherein the first dielectric layer is located between the first reflective layer and the second reflective layer, and the second dielectric layer is located between the second reflective layer and the third reflective layer.

[0009] By employing the aforementioned device, the alternating layering effectively enhances the reflection and refraction of light between layers, thereby improving the overall brightness and color saturation of the crystal. Simultaneously, the multi-layered structure helps optimize optical path difference, achieving a richer range of interference colors and further enhancing the crystal's optical performance and aesthetics.

[0010] Preferably, the thickness of the adhesion layer is 60-65 nm, the thickness of the reflective layer is 25-36 nm, and the thickness of the dielectric layer is 20-26 nm.

[0011] Preferably, the thickness of the adhesion layer is 63.58 nm, the thickness of the first reflective layer is 35.86 nm, the thickness of the second reflective layer is 31.42 nm, the thickness of the third reflective layer is 25.88 nm, the thickness of the first dielectric layer is 25.88 nm, and the thickness of the second dielectric layer is 20.19 nm.

[0012] Preferably, the adhesion layer is a chromium layer, the first reflective layer is a chromium layer, the first dielectric layer is a silicon dioxide layer, the second reflective layer is a silver layer, the second dielectric layer is a titanium nitride layer, and the third reflective layer is a titanium pentoxide layer.

[0013] By employing the aforementioned apparatus and using a chromium layer as the adhesion layer, the surface oxidation during chromium deposition facilitates lattice matching between the chromium layer and the crystal substrate, as well as the underlying coating layer, thereby enhancing adhesion and significantly improving the bonding strength between the coating layer and the crystal substrate. Furthermore, by controlling the thickness and material of each coating layer, a vibrant and colorful visual effect can be achieved in the crystal.

[0014] Preferably, a protective layer is provided at the bottom of the third reflective layer, and the protective layer is attached to the third reflective layer by roller coating.

[0015] Preferably, the protective layer is one of a paint layer and an adhesive layer, and the thickness of the protective layer is 5-10 μm.

[0016] By using the above-mentioned device, the protective layer plays a role in protecting the internal coating, enhancing the durability of the coating and the quality of the crystal, and significantly improving the service life of crystal products.

[0017] Preferably, the crystal substrate is made of glass or plastic.

[0018] Preferably, the light transmittance of the crystal substrate is greater than 90%.

[0019] By employing the aforementioned device, the crystal of this application has the advantage of lower cost, which not only enhances the aesthetics of the crystal but also makes it closer to the optical performance of natural diamonds.

[0020] This application has the following beneficial effects:

[0021] 1. In this application, the adhesion layer significantly enhances the bonding strength between the coating and the crystal substrate, effectively solving the problem of easy peeling of the coating in the prior art, thereby improving the product's service life and reliability. The reflective layer enhances light reflection, allowing light to be reflected back to the observer's eye more efficiently after refraction within the crystal substrate, thus enhancing the overall brightness and brilliance of the crystal. The dielectric layer has excellent anti-reflection properties, effectively reducing light loss during interlayer propagation and increasing light transmittance, resulting in a purer and more transparent visual effect for the crystal. The alternating stacking of the reflective and dielectric layers forms a multi-layer optical interference structure, which not only improves reflection efficiency but also enhances color saturation and layering, thereby making the crystal exhibit a more dazzling and colorful optical effect.

[0027] The present application will be further described in detail below with reference to Figures 1-2.

[0028] A crystal coating structure, as shown in Figures 1-2, includes a crystal substrate 1. The upper surface of the crystal substrate 1 has a multi-faceted structure, including small mesa 11 and multiple crown facets 12, while the lower surface has a planar structure, providing a suitable plane for subsequent coatings. An adhesion layer 2, a reflective layer 3, and a dielectric layer 4 are attached to the lower surface of the crystal via vacuum electroplating. The reflective layer 3 has three layers, and the dielectric layer 4 has two layers, with the reflective layer 3 and dielectric layer 4 alternately stacked. In this embodiment, the crystal substrate 1 is made of glass or plastic, and its light transmittance is greater than 90%, which not only improves the surface quality of the crystal but also makes it more closely resemble the optical performance of natural diamonds.

[0029] Specifically, as shown in Figures 1-2, the reflective layer 3 includes a first reflective layer 31, a second reflective layer 32, and a third reflective layer 33, while the dielectric layer 4 includes a first dielectric layer 41 and a second dielectric layer 42. The adhesion layer 2 is located between the crystal substrate 1 and the first reflective layer 31, providing excellent adhesion and ensuring a tight bond between the coating and the substrate, significantly improving the bonding strength between the coating and the substrate. The first dielectric layer 41 is located between the first reflective layer 31 and the second reflective layer 32, and the second dielectric layer 42 is located between the second reflective layer 32 and the third reflective layer 33. The alternating stacking of the reflective layer 3 and the dielectric layer 4 forms a multi-layer optical interference structure, which not only improves reflection efficiency but also enhances color saturation and layering, thus giving the crystal a more vibrant and colorful optical effect.

[0030] As shown in Figures 1-2, in this embodiment, the adhesion layer 2 is a chromium layer with a thickness range of 60-65 nm and an optimal thickness of 63.58 nm. This allows the surface oxidation during the chromium layer deposition process to easily form a lattice match with the crystal substrate and the lower coating layer, thereby improving the adhesion and significantly enhancing the bonding strength between the coating layer and the crystal substrate.

[0031] As shown in Figures 1-2, in this embodiment, the thickness of the reflective layer 3 is controlled within the range of 25-36 nm, and the thickness of the dielectric layer 4 is controlled within the range of 20-26 nm. Specifically, the first reflective layer 31 uses a chromium layer with a thickness of 35.86 nm, the first dielectric layer 41 uses a silicon dioxide layer with a thickness of 25.88 nm, the second reflective layer 32 uses a silver layer with a thickness of 31.42 nm, the second dielectric layer 42 uses a titanium nitride layer with a thickness of 20.19 nm, and the third reflective layer 33 uses a titanium pentoxide layer with a thickness of 25.88 nm. The alternating stacking of the reflective layer 3 and the dielectric layer 4 can achieve a richer range of interference colors. Combined with the multifaceted structure of the crystal's upper surface, it can achieve the effect of displaying different colors from different angles, further improving the optical performance and aesthetics of the crystal.

[0032] As shown in Figures 1-2, in order to further enhance the adhesion of the coating and reduce the peeling phenomenon, a protective layer is provided at the bottom of the third reflective layer 33. The protective layer can be a paint layer or an adhesive layer. In this embodiment, a protective layer with a thickness of 8μm is formed by rolling a curing adhesive at the bottom of the third reflective layer 33 to protect the internal coating from peeling off, enhance the durability of the coating and the crystal quality, and significantly improve the service life of the crystal product.

[0033] Working principle: By adding an adhesion layer 2 between the crystal substrate 1 and the reflective layer 3, the bonding strength between the coating and the substrate is significantly improved, solving the problem of easy peeling of the coating. At the same time, the alternating stacking design of the reflective layer 3 and the dielectric layer 4 makes full use of the optical properties of different materials, achieving an optimized balance between reflectivity and transmittance, thereby improving the aesthetics and durability of the overall structure.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
